Very Sorry to hear about this. From what I see the bumper is intact but the clips gave up and the headlight assembly is broken. I cannot see if there is any damage internally from the pic posted. The guesstimate from my understanding would be around 10k. Kindly share the details of any other damaged parts that I failed to locate here. The insurance company will accept the hit and run scenario here, so nothing to worry. Depending on the age of the car the depreciation percentage is calculated on the parts to be replaced. Keep us posted. Cheers, Pradeep.
